Test Method

1

Overcharge

No fire、No explosion

After standard charge, rest for 10mins; then charge at constant current of 3C5A to 10V.(or charge at 3C5A for 90mins).

2

Forced discharge

No fire、No explosion

The battery to be discharged with standard discharging condition, Inverse charge current =1C5A;time: ≥ 90mins

3

Short Circuit test

No fire、 No explosion

The battery to be fully charged with standard charging condition, and short the positive and negative terminals with wire resistance ≤50mΩ.Tests are to be conducted at 23℃±3℃ and at 55℃ ±5℃, keep 24h or case temperature decline to 20% of the max temperature ,test is over.

4

Crush test

No fire、No explosion

A battery is crushed between two flat surfaces. The applied force is 13 kN±1kN by hydrocylinder, Once the maximum pressure has been obtained or voltage decrease to 1/3 of nominal voltage sharply, then release pressure.

5

Shock test

No fire、No explosion

The full charged battery is fixed on shock table, to force a certain shock to three mutual vertical direction, in initial 3ms, the min. average acceleration is 75gn,the peak acceleration is between 125gn and 175gn.

6

Heating test (130°C)

No fire、No explosion

The cells are fully charged with standard charging condition, and put into incubator with nature air or cycled air convected, heat battery by velocity of 5°C ±2°C/min to 130°C±2°C,and maintain for 10mins.

7

TemperatureCycling Test

no leakage, no fire, no explosion

The fully charged batteries are placed in a test chamber and subjected to the following cycles: a) Raising the temperature to 75°C ±2°C within 30 minutes and maintaining this temperature for 6 hours. b) Reducing the temperature to minus 40°C ±2°C within 30 minutes and maintaining this temperature for 6 hours. c) Repeating the sequence for a further 9 cycles. d) After the 10th cycle, storing the batteries for 24 hours prior to examination.
